MACHINE FOR MIXING CONCRETE, 81.0.

SPECIFICATION forming part of Letters Patent No. 754,927, dated March 15, 1904:.

Application filed December 26, 1903. Serial No. 186,565. (No model.)

To all whom it may concern/.-

Be it known that I, JOHN E. KENISELL, a citizen of the United States of America, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvem ents in Machines for Mixing Concrete, &c., of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to improvements in concrete-mixers and machines for similar purposes; and its object is to provide a very simple, cheap, and efficient device which is strong,

vey it along the trough, and a further object:

is to provide the particular arrangement and combination of parts, all as hereinafter more fully described, reference being had to the accompanying drawings, in which- Figure 1 is a plan view of a device embodying the invention; Fig. 2, a central longitudinal vertical section of the same; Fig. 3, an end elevation, and Fig. A a perspective view of one of the agitating and conveying arms.

As shown in the drawings, A represents a suitable rectangular supporting-frame consisting of two parallel I-beams A, connected and spaced apart by tie-rods A provided with nuts A engaging the inner and outer sides of the webs of the beams. Near each end of the frame are secured transverse supporting-brackets formed of flat bars B, bolted at their ends to the top of the beams and provided upon their raised middle portion with bearings C. Supported upon the frame with its bottom resting upon the tie-rods is a trough D, semicircular or U-shaped in crosssection and secured in place thereon by braces discharge end being open and a portion of the bottom cut away at D to form a dischargeopening for the material. Ashaft E, supported near its ends in the bearings C, extends in the longitudinal axis of the trough, and onthis shaft are strung the arms G for agitating and conveying the material along the trough. These arms each consist of the blade portion G, which is so formed as to give it a lead-that is, the blade extends at a slight angle to the path of its rotatio'nso that as it turns about the axis of the shaft it will slowly feed the material toward the discharge end of the trough, said incline of the blade acting to push the material along during both its downward and upward movement in the material, and a sleeve portion G is formed integral with the blade to fit the shaft. Set-screws G are provided to secure the arms in any desired position on the shaft and permit of their being removed when there are too many to secure the best results, according to the work being done, or others may be put on. The arms are preferably set, however, to form one continuous spiral row, which extends once around the shaft, and thus but a few of the agitators are in the bottom of the trough at any one time and the shaft will turn'much easier than it would provided the same number of arms were used, but so set that the row extended more than once around the shaft, as more of the arms would be in the material at one time.

The shaft F may be driven in any suitable manner, a gear H on the end of said shaft, driven by a pinion I on a separate drivingshaft, being shown as the most convenient way where a gasolene-engine is used as the motive power.

As shown in Fig. 2, for the purpose of supplying Water to the trough to mix with the other material a water-supply pipe J is protrough above the same, said head being perforated along its lower side to allow the Water to escape in small streams.

Having thus fully described my invention, What I claim is- 1. In a mixing-machine, the combination of a supporting-frame consisting of parallel I-beams secured togetherby tie-bolts provided with nuts engaging the inner and outer sides of the webs of said beams, brackets secured to the upper side of said beams at each end of the frame, bearings on said brackets, a U- shaped trough having a closed and an open end and supported by the tie-rods, braces secured at one end to said beams and at their opposite ends to the sides of the trough near its upper edge, a shaft in said bearings extending in the axis of the trough, agitators on said shaft consisting of blades extending at an angle to the path of their travel around the'shaft to feed the material toward the open end of the trough, and means for actuating said shaft.

2. In a eoncrete'mixer, the combination of a supporting-frame consisting of two parallel I-beams secured together by tie-rods extending through openings in the Webs of the beams and provided with nuts engaging the inner and outer sides of said webs, a U-shaped trough having an open and a closed end and having its bottom cut away at its open end to form a discharge-opening, flat iron bars bent to form brackets and secured at their ends to the beams near each end of the trough, bearings secured to said brackets, a shaft in said bearings, agitators consisting of sleeves to engage the shaft and provided with blades formed to extend at an angle to the path of travel of the blades around the shaft and secured to the shaft in a spiral row extending once around the shaft, set-screws to secure the agitators to the shaft, a Water-supply pipe having a'perforated head extending longitudinally of the trough above the same near its closed end, and means for turning the shaft.

In testimony whereof I aflix my signature in presence of two Witnesses.

JOHN E. KENISELL.
